Heading into Game 2

Warriors update: The Warriors had one turnover in the first quarter and 13 for the rest of the game, many of the careless variety. Curry was particularly sloppy passing into traffic. … The Warriors could use more production from their usually reliable bench. The reserves scored 16 points on 6-for-16 shooting in Game 1 as the “Death Lineup” was on the floor a lot. Draymond Green, Klay Thompson and Curry each logged 40 minutes, all above their season averages.

Thunder update: Offensively, Oklahoma City role players did the job while Durant (10 for 30) and Westbrook (7 for 21) shot a combined 17 for 51 (33.3 percent) from the field. The rest of the Thunder players were 22 for 38 (57.9 percent). … Reserve center Enes Kanter, one of the keys to Oklahoma City’s big lineup that vanquished favored San Antonio in the Western Conference semifinals, contributed offensively in Game 1 with eight points in 18 minutes, but was a disaster on defense. Whenever he had to switch onto smaller Warriors players, they were able to drive around him or step back for 3-pointers. … Kanter and starting center Steven Adams were on the floor together for about an eight-minute stretch spanning the third and fourth quarters when Oklahoma City outscored the Warriors 26-13 to take a 95-91 lead. … In the first half, the Thunder had 10 turnovers and two offensive rebounds, but in the second half it had two turnovers and eight offensive rebounds.

Keys to the game: The Warriors need to do what they do best on offense: Move and pass the ball. When they do this, their shot selection winds up being so much better. … Can the Thunder’s Andre Roberson, a defensive specialist not known as an offensive threat, keep the Warriors’ defense honest? He was 3 for 3, including a 3-pointer in Game 1 while he was mostly guarded by Green, who cheated off him to help on other Thunder players.
